How to use this project: https://cantact.io/cantact/users-guide.htmlCANtactThe CANtact device is a single channel USB CAN interface. It can be used to connect to CAN bus systems, including cars, heavy duty vehicles, and industrial automation systems. CANtact works on Linux, OS X, and Windows.With a CANtact and an OBD-II to DE9 cable, it is very easy to get onto the OBD-II CAN bus of any CAN enabled vehicle.Getting StartedConnections & JumpersCANtact uses a USB-B cable to interface with your computer. These cables are commonly used to connect printers as well.The DE9 connector of the CANtact allows for two pin mappings for different use cases:Pins 7 (CAN high), 2 (CAN low), and 3 (ground) for standard CAN connectionsPins 3 (CAN high), 5 (CAN low), and 1 (ground) for use with an OBD-II to DB9 cable. This is compatible with the Sparkfun OBD-II cable.The pins can be selected using the jumpers on board.The final jumper is for CAN termination. Place the jumper beside the "CTE" marking to place 120 ohms across CAN high and CAN low. This is commonly used in development, when you are only interfacing with a single CAN device.CandleLight FirmwareTo use the tools discussed in this book, you must ensure your CANtact is running the CandleLight firmware. The firmware can be downloaded from Github.After downloading, follow the steps in Updating Firmware to perform the update.Updating FirmwareThe CANtact can be updated over USB. First, you will need to put the device into DFU mode by following these steps:1.Disconnect the USB cable from the CANtact2.Connect the two "BOOT" pins3.While the pins are connected, plug the USB cable into the CANtact4.The CANtact device is now in DFU modeThe next steps depend on what OS you are using.

Basic Raspberry pi wedgie to connect any 40 pin board to a breadboard

Hello, please see blog post here. https://audiodiwhy.blogspot.com/2021/09/ltc2645-pwm-to-voltage-can-we-get-audio.htmlI needed a MSOP 5mm 16 pin to PDIP adapter for breadboarding and testing an LTC2645, there are hard to find so I made my own BoB for this. I recommend getting a small stencil as well. Be patient and careful and inspect your work carefully but for me it worked!

In this tutorial, I am going to show you guys how to create a fire effect first using 4017 IC and then using an Arduino.I will also show you guys how to create a Cardboard Tank and a Burning Village. This was a small request from my son and my attempt to recycle some household junk. He loves the final built, I hope you guys also like it. Electronic ComponentsFor the electronic bit we need:1. 1 x IC 40172. 1 x IC 5553. 1 x 10uf Capacitor4. 1 x 220ohm Resistor 5. 1 x 1K Resistor6. 1 x 10K Pot7. Arduino Uno/Nano (whichever is handy)8. Red, Orange, White LEDs and9. Few connecting cablesUsing IC 4017The circuit is very simple. Basically its a forward chaser circuit using 4017 IC. The 555 Timer IC operates as a clock oscillator or clock generator. The output on PIN-3 goes high causing a shift.The signal from the 555 IC clocks the 4017 decade counter. Output of 555 timer IC on PIN-3 is given as an input to 4017 IC through PIN-14. Whenever a pulse is received at the input of IC 4017, the counter increments the count and activates the corresponding output PIN.By increasing or decreasing the value of resistance of the 10K pot we can adjust the speed of the chaser circuit.The BoardSo this is how my board looks like. I have 4 breakout boards in this 100cm x 100cm assembly.SolderingLets start by soldering the 2 resistances to the board. Then,lets solder the 10uf capacitor to the board. After that, lets solder the 10K pot. Next, lets solder the 2 IC bases and install the two ICs to the bases.I am not going to solder any LEDs directly to the board, instead I will solder them to separate boards and then connect them using ribbon cables.Lets do a quicks test before moving to the next step. Using water-color I painted a cotton ball to look like a fire ball. Looks perfect, isn't it? Using ArduinoThe same fire effect can also be created using an Arduino. The beauty of using an Arduino is that, by updating the "Blink Example Code" we can flash as many LEDs as we want. I will provide a copy of the code in the description below, however, it totally depends no you how you want to present it. Components For The Cardboard Tank And VillageTo create the DIY Tank we need:Cardboard Sheet A4 PaperPermanent MarkerScissor and a KnifeHot Glue GunOptional Plaster of ParisOptional Sandpaper Water Color and Coloring BrushesThe Template - TankSo, this is the template I created for the Tank's body. I will provide the link in the description below. Using a paper cutting scissor, I extracted all the shapes from the template. Cutting The Cardboard - TankThen I traced the paper-cutouts on pieces of cardboard and using both scissor and a knife I extracted all the pieces of cardboard that I need for this project.Joining Pieces - TankUsing a hot-glue gun I joined all the cardboard cutouts.Be very careful while using a hot-glue gun. Use gloves as much as possible to avoid the hot glue from burning your hand and fingers. By using wood-glue instead of hot-glue you can get a cleaner and stronger finish, but hot glue is faster. Hot glue can also be more forgiving as you can re-heat and re-glue if you're unsatisfied with your seam.Try applying the glue from the inner side as much as possible to leave the outer side neat and clean.Coloring - TankSo, this is how my cardboard Tank looks like. Using brown, yellow and black Acrylic Color I painted the body of the Tank. It totally depends on what color you want to apply; but, please do not paint it red or pink, ha ha....By changing the shape and size of the canon, body, caterpillars or the top section of the tank, or by applying a different set of colors you can generate a new model and add to your DIY collection.Cardboard BaseNow that we have our Tank ready lets start building the burning village. Using a precision knife I am sculpting the cardboard pieces and then joining them using hot-glue.On my way back from work, I found this amazing piece of art. I am going to use a bit of this to create some dead trees in this project and the rest I will use in my upcoming projects. I added a bit of POP to the base to give it a bit of rough and rocky look, however it is totally optional and to be very frank absolutely unnecessary.Coloring The BaseNext, using different combinations of Acrylic Colors I painted the house and the ground bit.So, this is how it finally looks like.Now, to conclude I added the electronics bit to the base and the burning house. Let's do a quick test to see how the fire looks like by placing the painted cotton ball. Bang, that looks good, isn't it?DemoSo this is how the final setup looks like.

Provides a simple but flexible isolated or common ground opto-isolator board. Use 4N35 or similar opto-isolators. Size resistor for input voltage... for example, if input voltage is ~12V, use a 1.2 to 1.5K resistor. Resistors can be either 0805 SMD or thru-hole type (pads exist for SMD under the space for the thru-hole resistors). J1 will tie the two input grounds together. J2 will tie the input ground to the output ground (usually used with J1). You may use pin headers for the jumpers or just us a wire. This board is intended to used for example with an Arduino board using pull-up inputs and low-active logic, that is, a high input on the opto-isolator will close the transistor and pull the Arduino input to ground, making a low on that Arduino input equal a high on the opto-isolator input.

Control shield for the MPRSx8 Relay Board(https://www.tindie.com/products/next_evo1/wifi-8x-mains-relays-board-for-home-automation/)(https://esp8266-projects.org/2016/11/mprsx8-relay-board_for_home_automation/)This control shield for the MPRSx8 WIFI 8x MAINS Relays board for Home Automation allows for control of the board via manual inputs in the form of a 4 position DIP switch and potentiometer connected to the ESP8266-12 on the MPRSx8.The use case was to build a device that could control 2-8 lights via relay in a selectable pattern and speed. The code written for this shield allows for a selection of 16 different pattern programs via the DIP switches, and variable speed of the pattern via the potentiometer.

Not all people know about that Creality 1.1.X boards have other accessible IO port, not just the commonly used Pin27. This tiny board can expose Pin29 for adding more features. You need to unsolder the factory 16V 100uF capacitor and re-solder it to the new board. The exposed V pin is 5V!It has a JST 3P connector, the same one that any Filament Runout sensor uses.Crosslink explains it very well:?

As the techies know, Sparkfun offers a very capacble and attractive Series of IoT solutions with Its MicroMod Ecosystem.We went a head and designed a Custom, Low cost ESP32 Micromod Processor in M.2 Form factor.MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals utilizing the M.2 standard.Checkout Sparkfun Micromod Series:https://www.pcbway.com/project/shareproject/techshare.aspxKey Features:32Bit RP2040 CPU448 KB ROM520 KB SRAM16 KB SRAM in RTCQSPI supports multiple flash/SRAM chips34 × programmable GPIOs12-bit SAR ADC up to 18 channels2 × 8-bit DACUpto 10 × touch sensorsRP2040 Datasheet:Flash(4MB)External Flash and SRAM ESP32 supports multiple external QSPI flash and SRAM chips. More details can be found in Chapter SPI in the ESP32 Technical Reference Manual. ESP32 also supports hardware encryption/decryption based on AES to protect developers’ programs and data in flash. ESP32 can access the external QSPI flash and SRAM through high-speed caches.Up to 16 MB of external flash can be mapped into CPU instruction memory space and read-only memory space simultaneously. – When external flash is mapped into CPU instruction memory space, up to 11 MB + 248 KB can be mapped at a time. Note that if more than 3 MB + 248 KB are mapped, cache performance will be reduced due to speculative reads by the CPU. – When external flash is mapped into read-only data memory space, up to 4 MB can be mapped at a time. 8-bit, 16-bit and 32-bit reads are supported.External SRAM can be mapped into CPU data memory space.SRAM up to 8 MB is supported and up to 4 MB can be mapped at a time. 8-bit, 16-bit and 32-bit reads and writes are supported.M.2 Form FactorM.2, formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. This Standard is completely compatible with Sparkfun MicroMod Series.MicroMod InterfaceMicroMod is a compact interface created to connect a microcontroller to various peripherals. You can generally think of the MicroMod system as a "brain" plugging into a "carrier board." A MicroMod processor board is approximately 22x22 mm, and can insert into any MicroMod carrier board. Whereas the original M.2 standard was designed for swapping out peripherals (a user could swap one solid state hard drive for a larger one, for example), the MicroMod standard is designed for swapping out controllers. For example, a user can start with a powerful processor, and then change to a low power controller to extend battery life.Photo Credit (Sparkfun)Dimensions:Size:22mm x 22mm1x Spherical M.2 Screw HolePCB Information:Signal Layers:2None Signal Layers:10Components:18Pads:164 Surface Pads:163 Plated Through-hole Pads:0 None Plated Through-hole Pads:1Holes:0Vias:46Nets:45/52Length of Tracks:548.03mmCopper Areas:2Open Source Hardware:This is an Open Source design with all the files and documentation available to General Public Under GNU V3.0 License.
